Planning on visiting India for a month between end of Feb to End of March

Questions:

What is the general timeline for getting the bio-metrics appointment? From what I have read so far it's usually a month after the 5 year completion. Which in my case appears to be month of March and that's when I am planning on travelling. What are the impacts of missing the scheduled bio-metric, if at all?

I looked at the processing times (https://egov.uscis.gov/processing-times/), for naturalization is the typical wait between bio-metric and interview / Oath. I am confused how the wait time is split? Do they wait to schedule bio metric or wait to schedule the interview?

Can I pick a processing center of my choice or it's auto selected at the time of application? There are couple of processing centers in TX. Do I have an option to pick a processing center outside of TX as well? Are interviews and oath ceremonies scheduled onsite at the center?

It makes sense for me to get my indian passport renewed since it's expiring a month after 2/14/2019?
